VLAN CONFIGURATION
Configuring VLAN Behavior for Interfaces
You can configure VLAN behavior for specific interfaces, including the default VLAN identifier (PVID), accepted frame types, ingress filtering, GVRP status, and GARP timers.
Command Usage
•GVRP – GARP VLAN Registration Protocol defines a way for switches to exchange VLAN information in order to automatically register VLAN members on interfaces across the network.
•GARP – Group Address Registration Protocol is used by GVRP to register or deregister client attributes for client services within a bridged LAN. The default values for the GARP timers are independent of the media access method or data rate. These values should not be changed unless you are experiencing difficulties with GVRP registration/deregistration.
Command Attributes
•PVID – The VLAN ID assigned to untagged frames received on the interface. If the (CLI) switchport mode is set to trunk (see page
•Acceptable Frame Type – Sets the interface to accept all frame types, including tagged or untagged frames, or only tagged frames. If only tagged frames are accepted, the switch will only accept frames if the frame tag matches a VLAN to which this interface has been assigned. (Default: All)
•Ingress Filtering – If ingress filtering is enabled, incoming frames for VLANs which do not include this ingress port in their member set will be discarded at the ingress port. This will not affect VLAN independent BPDU frames, such as GVRP or STP. (Default: Disabled)
